' Application filed June 20, 1916. Serial No. 104C744.

To all whom may concern:

claimed.

a Be it known that I, MYHALZ H.'D. PRIDDY,

a citizen of the United States, residing at Richmond, in the county of Contra Costa and State of California, have invented new and useful Improvementsin Dairy cans, of which the following is a specifieatlon.

This invention relates to improvements in cans and other like vessels, especially dairy cans such as are used in the transportation of milk and other dairy products, the object. of the invention being to provide an 1mpreved can of this type which is extremely light, is very strong and durable, is noncorrodible, and is adapted to be easily handled and is destitute of seams or rivets in the sides, shoulder, or neck.

Fig. 3 is a similar view ofthe lower portion ofthe can.

Figs. at, 5, and 6, are detail views. Fig. 7 is a detailed plan of the collar 'or V neck ring.

Fig. 8 is a detailed sectional view showing one of the catches engaglng the flange of the collar.

The body 1 of my improved an is made of aluminum and is formed with an upwardly contracted shoulder 2, and a cylindrical'neck' 3. In themanufacture-of the can, the body with the shoulder and neck are made all in one'pieceby first running the same from molten metal into a mold of the required shapeof the can. .The mold or shapeis however less in size but thicker than the can when finished, As soon as the can form can be removed from the mold, the same is placed between two rollers which roll the metal while still hotand the rollmg is continued until a wall of the required thickness is obtained- Hence the can body is integral and is entirely without a seam or rivet.

The bottom 4 is also made of aluminum and is pressed from the metal in hot sheet form. immediately'after the metal has been coole'd from the molten state to a hardened state. The bottom is concaved as shown and is formed with a surrounding-downwardly extending flange 5, which is riveted snugly in the lower end of the body 1 and is riveted thereto as at--6.. I

. The cover 7 is also made of aluminumand is pressed in the same manner as the bottom and is adapted to fit snugly around the neck of the can.

7 At the base of the can is a ring 8 which is preferably made of malleableiron but which maybe made of any suitable material. The base ring is formed at its inner side with a channel 9 to receive the lower edges of the can body or wall and the flange 5 of the bottom and the outer wall 10- formed by the channel is higher than the inner-wall 1.1 and extends around the base of the body. Thebase ring'is of greater diameter than, and

extends outwardly from the body,as at 12,

ing flange 13 which bears on the floor and supports the can.

To further protect'the bottom ofthe can, I provide a sheet'met'al disk 14 which is; fitte! in'g' under the portio; l 12- of the base extends across th same. p r

A collar 15,- wnich isright angular in cross section, is fitted around the base of the neck, so. that its annular flange 16 projects outwardly from the neck. This collar is and is formed with an outer depending bear-v also preferably made of malleable iron or may be made of any suitable material and is provided ,with notches 10 A truss ring 17 is fitted lower portion of the shoulder 2 of the can,

the wall of said truss ring having a cylindrical portion 18 which extends around the '95 larger cylindrical portion of the can body and also having a frusto-conical portion 19, which fits aroundthe shoulder.

flange 12 of the base ring and also through the disk 141 and are provided with nuts or other suitable s'ecuring'devipes 23, the upper around'the larger The truss 'ring also has an outwardly extending an-' ends of the truss'rods being provided with hooks 24:,the bills of which are vertical'and extend downwardly through openings'in the flange 16 of the neckri'ng 15-" V I The can body being made of aluminum, is extremely light, but is also comparatively soft, the base'ring, tmssfring, neck and truss rods serving to protect the can and prevent it from being dented and deformed and at the same time greatly facilitating the handling of the can. To'enable the can to be readily lifted, the truss ring is provided at opposite sides with inverted U-shaped lifts or handles 25 as shown.

Secured across the top of the cover 7 is a flat steel spring 26, having down turned ends or arms 27, which are provided with catches 28, for engaging in the notches 10 of the flange 16 of the collar, and thereby securely and yet detachably fasten the cover, and also prevent the cover from slipping when the can is tilted androlled.

The cover is also provided with a handle ring 29, the diameter of which exceeds that of the cover. Said handle ring is connected to and secured above the cover by means of a suitable number of braces 30. These braces project a slight distance below the lower edge of the cover, bear against the upper side of the collar 15 and hence prevent any weight which may be placed on the can from being imposed upon the neck of the can.

When the cans are arranged, one above the other, the metal disk 14: of one of the cans bears on the handle ring 29 of the next can below and hence the top and bottom of each can are protected.

By grasping the handle ring and inclining the can so that one side of its base ring bears on the floor, the can may be readily rolled in any'desired direction as will be understood.

Having described the invention, What is claimed is: I

1. A can of the class described having protecting means including a neck ring having an outstanding flange provided with notches, and a cover for the can having spring catches to engage the notches and under the flange of the neck ring and detachably securing the cover in place.

2. A can of the class described having a neck ring and also having a cover, a. handle ring above the cover and braces connecting the handle ring to the cover and projecting slightly below the cover and bearing on the neck ring. a

3. In combination with a canhaving an upwardly contracted shoulder and a cylindrical neck-of less diameter than the body of the can, a neck ring on the neck of the can, a truss ring around said shoulder, abase ring under the bottom of the can, truss rods connecting the base and neck rings and having inwardly turned upper portions and bearing against the truss ring, said truss rods having their upper ends detachably engaged with the neck ring and having their lower ends arranged in openings in the base ring a disk fitted under the base ring and spaced from and protecting the can. bottom, said-rods extending also through openings in said disk and nuts on the lower ends of the rods and bearing against the under side of said disk. I I

In testimony whereof I aflix my signature.
